Limited to the dash cam working environment, technology, cost, etc, the night vision effect of dash cam is generally poor, this is a present status of industry.

At night, dash cam mainly uses the external light source such as street light, car headlights, etc, some dash cams may be equipped with LED light or infrared LED light to supplement the light source for the dash cam shooting, but these auxiliary small light have very little effect as these light will be reflected by the front windshield, and the car insulation film will absorb the infrared light, the night vision effect depends on the quality of camera lens, it has little to do with the auxiliary lamp.
